The　remote　appliances　control　system　based　on　the　Android　smart　phone　is　designed　and　realized.　A　user　logs　into　the　smart　phone　interface,　and　clicks　the　buttons　gently　to　send　message　commands　which　will　be　transmitted　to　home　information　center　through　the　GSM　network.　Then　the　ARM　processor　recognizes　the　specified　command,　and　controls　the　home　appliance　switches　in　the　wireless　radio　frequency　manner　to　achieve　remote　control　of　appliances　ultimately.　This　paper　focuses　on　the　design　of　Android　terminal,　the　communication　between　ARM　and　GSM　module,　the　realization　of　the　wireless　module　device＇s　driver,　the　difficulty　in　supplying　the　appropriate　low-voltage　DC　for　MCU　and　wireless　module　just　by　a　single　live　wire.　The　system　has　the　features　of　easy　installation　and　low　cost,　and　the　hardware　and　software　can　be　customized　and　extended.　What＇s　more,　the　users　can　manipulate　appliances　anytime,　anywhere,　letting　our　houses　become　more　and　more　automated　and　intelligent.
